So I have been shooting my PCC with titegroup pushing 147 gr projectiles. I will using a new 147gr fmj and bought a new barrel so I need to develop a new load. Just for record, I have the mbx barrel which is basically 13" before the pinned comp. I have titegroup like I have been running but I have winchester autocomp for my open gun and was wondering if I should try that? What are your thoughts titegroup or autocomp?? I hate to use it just yet because I have a lot of titegroup but I have some VihtaVuori N320 as well.
